Engineering Geology?Engineering Geology?

“Penerapan ilmu geologi pada praktek rekayasa dengan tujuan agar faktor-

faktor geologis yang mempengaruhi lokasi, design, konstruksi,pengoperasian & pemeliharaan pekerjaan dapat benar-benar dikenali &

disediakan dengan cukup.” (The American Geological Institute)

Engineering geology is the application of geological data, techniques andprinciples to the study of rock and soil surficial materials, and ground water.

This is essential for the proper location, planning, design, construction,

operation and maintenance of engineering structures. Engineering geology

complements environmental geology, or hydrogeology.



What does Engineering Geology study?

Rock, Soil, water, the interaction among

themselves, and with engineering

materials and structures



Why Engineering Geology matter?

Serve civil engineering to provide information inthree (3) most important areas:

–Resources for construction;

•Aggregates, fills and borrows.

–Finding stable foundations;•Present is the key to the past –geology

•Past is the key to the future –engineering

–Mitigation of geological hazards

•Identify problems, evaluate the costs,provide information to mitigate the problem.

Engineering Geology

- Established in 1928 after

failure of the St. Francis Dam;

- More physical geology

oriented;

- More quantitative;

- Focused on engineering

construction.



Main reasons for dam failure:

-Sedimentary rocks on the west lost strength when it is wet;

-The fault separating the west and east rock formations stated to leak water;

- Schist on the east increases pore pressure and lost shear strength after wet.



Engineering geologist contribute to the design of structures

such as the Alaskan pipeline near Fairbanks and many other

edifices. The pipeline was built in the 1970s to transport crude

oil from the Alaskan North Slope to the port of Valdez in

southern Alaska. Ground conditions near the surface

(permafrost and other processes) and those at depth (substrate

conditions, potential seismic activity, position of faults, etc.)

must be clearly understood and taken into consideration to

guarantee the integrity of engineered structures.

The photograph shows the raised pipeline (to prevent warm oil

from melting the permafrost) and the staggered shape of the

pipeline (to allow elasticity during earthquake shocks).
